I am in a similar situation. I had a bad pap smear, followed by another test done by my gynecologist. He then sent me to a cancer specialist who did a cone biopsy. this is an outpatient surgical procedure. I was told that that procedure can be used diagnostically as well as a form of treatment. It can be a treatment if what is found is only precancerous, and/or if the perimeters are all clean, which means that the it doesn't appear that the cancer cells have spread beyond what tissue they have taken out.
If you have not had a cone biopsy or a LEEP procedure as of this point, and they have only found pre-cancerous cells, then I would enquire about having that done first!!!
In my case, the cone biopsy showed that I had some small cancer cells as well, and that one perimeter was not clear... and so, they are recommending now for me to o a vaginal hysterectomy.
Good luck to you and I hope all is well. @cocowill
